Description

**If you've never tried DaTuner and like leaving less than 4 stars without a comment, please save your money; this app is terrible! :)**

For the rest of you, DaTuner is one of the smallest tuners on the market clocking in at ~ 800kB!

Super precise from A0 all the way up to > C8! The multi-harmonic strobe functionality in Pro gives almost immeasurable precision all the way down to the lowest notes, and is intuitive and readable.

Extremely fast, with latencies and averaging all adjustable via the settings menu. If it's fast on 5 year old Android devices running Android 2.1 without fixed-point support, then it will be fast on your device! :)

The PRO version also features an accurate pitch pipe and and was reviewed by Android Central:

"For the Android-loving musician, I think DaTuner Pro is easily the best tuner you can have on your device. I used to give that title to *see review!*, but DaTuner has proven to be so powerful, easy to use, and accurate, it'd be foolish to not use it."

DaTuner's display is easy to read; nearest note and octave is displayed in a giant, easy to read font in the center of the screen, and frequency in hertz plus error in cents is displayed at the bottom of the screen. Sensitivity is auto-adjusted, but can also be adjusted by touch via a bar on the left-hand side of the screen, and the speed/accuracy of the algorithm and the relative frequency (if other than 440Hz) can be adjusted via the configuration menu.

There is no "dead zone" with this tuner app as is the case with many other apps. Instead, the whole display turns green when the incoming frequency is within a configurable range of the target frequency and you can still see small changes in pitch even within the "in-range" area. Both the "in-tune" range and the colours shown for sharp and flat can be configured in this version.

Screen and filter lock allow you to select the note that you would like to tune to, with filter lock ignoring anything outside of the range of the note you wish to tune, which is useful for tuning in noisy environs.

Features:1.) No dead zone - screen changes to green when tuning is good.2.) Auto-Sensitivity - no configuration required.3.) Bright, easy-to-read display.4.) Quick, accurate and precise.5.) Screen lock: Lock to the note you want to tune, even if extremely out of tune and make your way up/down to it.6.) Filter lock: Lock and filter to a specific note and filter out everything outside that note's range.7.) Ad-free!8.) Reference frequency adjustment for orchestra tuning, adjustable manually or by letting the app listen to another reference.9.) Some instruments can be selected - more to come!10.) Choice of colors for sharp/flat/in-tune11.) Sample rate range 8kHz - 48kHz.12.) Transposition.13.) Temperaments. You can modify the ones that exist or add your own using a text editor. The temperaments are saved on your external memory under the /DaTuner directory.14.) Notation (ie Solfége, English, English sharp, English flat, Northern European.)15.) REAL strobe tuner display, with up to 4 overtones!16.) Pitch pipe with multiple overtones, so it is audible even when playing low tones.17.) Custom instruments/temperaments/tunings via a .xml file.

This strobe tuner is not like some others around that "emulate" "virtual wheels and flash lamps." Why use 100 year old technology - the Strobe in DaTuner is based on a modern DSP algorithm and is just as accurate as an old strobe tuner but is easier to read.

Not worth five stars? Please email me/leave a comment with your rating! Thanks!

Bogus note value in OnePlus 5. It used to work on V20 but it shows completely wrong octave. Other tuning apps are working fine though.

Outstanding. Best tuner I owned. I manufacture wooden flutes and I need to adjust the A4 reference for atomospheric conditions; this app does it in 0.1Hz steps which means I can be really accurate! Thank you.

I've been using the free version tuner for years and found it to be very fast and highly accurate. The developer needs to be rewarded for his efforts and constant updates, so I upgraded to his Pro version because he deserves it! Great job developer and continued success!!

Use as main tuner for my fiddle and mandolin. Do not need anything else. Cannot fault. Go Pro to reward developer for great work.

Michael Convertino

Prefer it over my Boss pedal tuner that cost me a hundred bucks.

DaTuner is a very fine tuner application. There is nothing gimmicky here. For a number of years, instead of focusing on the graphics, the work has been on the refinement of this product. It is feature rich and easy to use. Instead of practicing satisfied neglect, the developer keeps working to make it better. Buy it, use it.

Drone should keep on playing after locking device. Hiding error in cents displays +1000000.0C. App should drop the Holo design. Edit: 2 months since this was reported, still no fix. Edit2: alright I'm done with it. Avoid if you care about regular improvements and timely bug fixes.

just bought it :) after an update 01/29/2016 (manila) -now background is pure black!thank you! you deserve 5stars!!! ..and more updates coming in! nice! I wish there's an option to change the background color. I have two android phones and installed it on both. yeah, there's no problem with the blacks on my screens. what you have is a dark gray and NOT BLACK. you'll notice it on the bottom bar where it shows you when you're in tune. the round part of the tuning bar has background black edges and that's black. you'll see it when it moves. that's Black behind the tuning bar. I like it black not gray. 4/3/2016 update: nice!love it!

Quick, accurate I use this in a band for practice. Its quick, accurate with numerous options for adjusting range and sensitivity. As a test I tuned my electric guitar while our drummer, bass player and singer were playing in the room, and it listened for exactly the notes it said it was listening for. Impressive. I use it for gigs and also in the studio this month, with no faults at all. Band is Into the Badlands btw :)

Finally found the one After trying more tuners than I care to mention, it seems I've finally found the no-frills solution I've been searching for. Simple, gets the job done quick and accurately, yet rather customisable.

Excellent Tuner. I play a lot of different instruments and the chromatic tuner mode is excellent. It can't seem to hear the low "B" string on my 5 string Bass, but assume that could be a function of my phones microphone. All said this is the best tuner I've found.
